The Probotector is a fighting robot that was developed in top secret by a special scientific mechanized unit.

Probotectors are the main protagonists in most European game versions of the Contra series. Probotector eventually would become its own separate character in later sequels and reboots.


When Konami released the NES version of the original Contra in the PAL region (Europe and Australia), they modified the game by replacing the original main characters and most of the human enemies with robotic counterparts, re-titling the game as Probotector (a portmanteau of "robot" and "protector"). The two new protagonists, RD008 and RC011, replaced Bill Rizer and Lance Bean, respectively. This was presumably done due to the German Federal Agency BPjM, which banned the sales of media deemed too violent for children, including "content which glorifies war", thus requiring the change to robotic characters.

In Contra 4, a Probotector appears as a secret character and received something of a canon update; Probotector units are armed recon robots specifically used in areas normally too dangerous or threatening for humans to enter, an open reference to their appearance as the protagonists of the early European Contra games. Much as was the case for Scorpion and Mad Dog in Contra 4, Probotectors canonically served alongside Bill Rizer and Lance Bean during the first Galuga Island conflict.



Note: Years indicate when the versions that include the Probotector characters were released, not the original release date of the games.


  • In Contra 4, after completing twelve challenges in "Challenge" mode, Probotector, the robot character from the old European versions of the Contra series, will be unlocked.
    • It is worth mentioning that Contra 4 was never released in Europe.



  • The European version of Contra: The Alien Wars is called Probotector 2. As such, both "Probotector" games for the Game Boy form a separate subseries.
  • Browny, a tiny robot protagonist appearing in Contra: Hard Corps, bears a notorious resemblance to a Probotector, likely being a nod to them with a chibi design.
    • Browny's serial number is CX-1-DA300; in the European version of the game, all the rest of the protagonists were changed to combat robots closely following Probotector-like designs; also, their names were changed as different models of the CX series (Ray to CX-1, Sheena to CX-2, Fang to CX-3 and Browny to CX-4).
    • In Contra: Return, a pair of combat robot characters were introduced called Bull and Scar who bear a strikingly similar design to the Probotectors (most likely being reimagined/modernized versions of them), who also belong to the CX series (although in that game's alternate universe), these being CX-1-DA-1000 and CX-1-DA-2000, respectively.
  • In Contra 4, there is an enemy called Proboterror. Fittingly enough, they are Probotector units corrupted and altered by Black Viper's forces. In addition to a standard humanoid form, they can reconstitute themselves if destroyed, adopting the form of either a dog-like recon robot or an armed combat walker.
  • In Contra 4, the playable Probotector has three alternate colors. In addition to the standard gray RD008 color scheme, there is also a blue RC011 color scheme, a gold color scheme and a dark-purple color scheme.
